Se it lqnnwn that i, Fiumi L. Srssiofs, :i lCitizen' of the llnited States, residing at (`l|nnl ns. in the county of Franklin and Stute nt' Ohio, have in rented Certain new und useful Improvements in Mining-Machines, (if which the fnllmi'ing :i Specification, refermer living' haul lierrin te the reeeeinpn. n ving iirziriingg.

The principal object of the invention is tn prmiile nn innprnwrl menne for effecting the n'mrrgfinent of the iffirrage or entier frame with respect te the innin or Stnliionnry frame. i

Nith this improved construction the foreeS fire bnlnneeii :it the opposite sifles of the cnr ringe with the result that there is nn temi ency for binding or cramping nt the fuicles. Preferably, the winding mechanism for the rope is mounted on the Carriage, so as to he driven by the same motor which drives the cutting mechanism. Preferably, alsa, I pr@ vide two rope mechanisms, me for advancing the carriage and the other for retract ing it, in@ tvm rrinfihnisims being similar inc enel nther. l

A further object of the inventinn is te provide means whereby one of the Same ropes which is used for moving the carriage on the freine een nis-n be used for moving the r-lifile machin bodily from point to point izhent a iz'iine i @ther nlijee-f: eli' the. invenien will be isp- ;mrent from the fellmring description and ein iins.
